The Long Utopia
New York Times Bestselling Authors
The fourth novel in Terry Pratchett and Stephen Baxter’s internationally bestselling “Long Earth” series, hailed as “a brilliant science fiction collaboration... a love letter to all Pratchett fans, readers, and lovers of wonder everywhere” (Io9)
2045-2059. Human society continues to evolve on Datum Earth, its battered and weary origin planet, as the spread of humanity progresses throughout the many Earths beyond.
Lobsang, now an elderly and complex AI, suffers a breakdown, and disguised as a human attempts to live a “normal” life on one of the millions of Long Earth worlds. His old friend, Joshua, now in his fifties, searches for his father and discovers a heretofore unknown family history. And the super-intelligent post-humans known as “the Next” continue to adapt to life among “lesser” humans.
But an alarming new challenge looms. An alien planet has somehow become “entangled” with one of the Long Earth worlds and, as Lobsang and Joshua learn, its voracious denizens intend to capture, conquer, and colonize the new universe — the Long Earth — they have inadvertently discovered.
World-building, the intersection of universes, the coexistence of diverse species, and the cosmic meaning of the Long Earth itself are among the mind-expanding themes explored in this exciting new installment of Terry Pratchett and Stephen Baxter's extraordinary Long Earth series.

Terry Pratchett
Terry Pratchett’s work was nothing short of magical, blending satire, wit, and a deep love for the absurd with stories that could make you laugh, think, and occasionally question reality. Born in 1948 in Beaconsfield, England, Pratchett's sharp humor and keen observations of human nature started early. After a series of journalistic jobs and a stint in publishing, he found his true calling as a writer of fantasy—albeit with a twist.
Pratchett’s most famous creation, the Discworld series, is a sprawling, multi-layered universe filled with quirky characters, sharp satire, and an unrelenting exploration of the complexities of society. The series—spanning over 40 novels—introduces readers to a world supported by four giant elephants standing on the back of Great A’Tuin, the giant turtle swimming through space. It’s a place where witches, wizards, and talking cats wander through settings that are both fantastical and familiar, a perfect mirror to our own world, full of politics, absurdity, and endless curiosity.
